NOSE-MOUNTING FOR EYEGLASSES.

Specification of Letters Patent.

Patented Oct. 28, 1919.

Application filed January 13, 1919. Serial No. 270,894.

To all whom it may concern:

Be it known that I, J osnrn E. HIGGINS, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented certaln new and useful Improvements in Nose- Mountings for Eyeglasses; and I do declare the following to be a full, clear, andexact description of the invention, such as w ll enable others skilled in the art to which it appertains to make and use the same.

This invention relates to nose mountings for eye-glasses, and it relates more particularly to certain improvements upon my nose mounting covered by Patent No. 1283764, dated November 5, 1918.

One object of this invention is to provide a pair of cooperative nose clamping mechanisms each of which comprises a single spring which performs the dual function which is effected by two of such sprlngs in my patent above referred to.

Another object is to provide a pair of nose engaging plates which are pivotally mounted so as to obtain a greater range of flexibility or conformity than has heretofore been obtained.

Other objects and advantages may become apparent to persons who read the following details of description in connection wlth the accompanying drawing in which:

Figure 1 is a top plan view of my 1mproved eye-glass mounting, one of the nose clamping mechanisms beln omitted.

Fig. 2 is a similar plan view, one of the nose clamping mechanisms being omltted, and the other being in its open or abnormal position.

Fig. 3 is an end view of the bridge bar and one of the nose clamping mechanisms.

Fig. 4 is a perspective view illustrating the bridge bar, one of the supporting levers and one of the nose clamping members which is normally pivoted on the supporting lever.

Fig. 5 is an edge view of one of the nose engaging plates and a fragmentary portion of the nose clamping member to which it is pivotally secured.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, the bridge bar 6 is provlded with the usual strap 7 to which the lenses are secured, the middle portion 8 of the bridge bar being bowed in the usual manner, and a portion'between each strap 7 and the middle portion 8 being formed into a bend or loop 9 which may be manipulated (by bending) so as to adjust the focal centers of the respective lenses 5. Between each loop 9 and the central arch or bowed portion 8, the bridge bar is broadened and apertured at 10, and screws or studs 11 are fitted in these apertures and extended upwardly and constitute pivotal elements on which are mounted a pair of combined supporting and operating levers 12. One of these members is more clearly shown separately in Fig. 4 and constitutes one of the several features of my invention. Each lever or supporting member 12 is preferably stamped from sheet metal and is formed with a shoulder or abutment 13 and a manipulative element or handle 14:, being also formed with apertures 15 and 16. The aperture 15 registers with one of the apertures 10 of the bridge bar 6 and receives one of the studsll and is thereby pivotally secured to the bridge bar. The aperture 16 receives a stud 18 which pivotally connects the member 12 with one of the two intermediary clamping levers 19. It will be seen, therefore, that each link 12 has pivotal connection both with the bridge bar and with one of the levers 19.

The bridge bar 6 is provided with abut ments 20 against each of which an arm 17 of one of the levers 19 is adapted to move, and which limits movement of the members 12 and 19 to one another. Each member or lever 19 is provided with an aperture 22 through which a pivot 22 extends and pivotally connects it with one of the nose guards 28. Each member 19 is formed with shoulders or abutments 19 and 19*, which limit the movement of the guards 28 on their pivots 22. By means of this limited pivotal movement of each guard 28, it is per mitted to perfectly and easily conform to the contour of the wearers nose, while the shoulders 19 and 19 retain the guards in such relation to the members 19 that they may be fitted to the nose without being first adjusted individually.

A single-coil spring 23 is provided for each pivot 18, and the coil (or helices) thereof encircles the shank of the pivot or screw 18, while one end of each spring engages the adjacent lever 19 as indicated at 23, the other end of the spring 23 engaging the stud or abutment 13 of the lever 12. The coil 24 of each spring may consist of one or more turns or helices, and it is described herein as a single-coil spring to distinguish 1t from the double coil spring disclosed 1n applicants patent above referred to.

Each of the levers 19 combines with the contiguous guard 28 to form a self-adjustlng nose-clamping jaw.

Referring to Figs. 2, 3, and 4,- it will be seen that the bridge bar 6 is provided with offset portions 29 adjacent to the studs or abutments 20, and that this shape of the bridge bar allows each lever 12 to cross the bridge bar between the adjacent abutment 20 and the adjacent straps 7, so that the offset portions 29 of the bridge bar serve as abutments to limit movement of the levers 12.

The levers 12 has a similar function as the links 12 of my patent above referred to, that is, supporting the intermediary levers and permitting movement of the latter relative to the bridge bar; these levers 12, however, have the additional function of operating or actuating the intermediary levers, being provided with the manipulative ele ments or arms 14 for this purpose.

In fitting this eye-glass mounting to the nose of a user the handles 14 are drawn toward one another, and this causes a movement of the pivots 18 away from one another, carrying the intermediary levers 19 therewith. However, the arm 17 of each intermediary lever is intercepted by the contiguous abutment 20, and this causes each intermediary lever to swing on its p vot 18 against the resistance of the contiguous spring 23, with the clamplng mechanisms in the open position, as indicated in Fig. 2. The mounting is now placed over the users nose, and the handles 14 are released, so that the springs 23 not only swing the levers 19 on their pivots, but also swing the levers 12 011 their pivots, thereby bringing the plates 28 in clamping engagement with the users nose.

Although I have described this embodiment of my invention very specifically, it is not intended to limit this invention to these exact details of construction and arrangement of parts, but I am entitled to make changes within the scope of the inventive idea disclosed in the foregoing description and following claims.

What I claim as my invention is:

1. An eye-glass mounting comprising a bridge-bar, a pair of combined supporting and operating levers pivotally mounted on i said bridge-bar, a pair of nose-guards, a pair of intermediary levers pivotally mounted on said combined supporting and operating levers and having said noseguards pivotally mounted thereon, and elastic means cooperative with said intermediary levers and nose-guards to clamp a persons nose.

2. An eye-glass mounting comprising a bridgebar, a pair of combined supporting and operating levers pivotally mounted on said bridge-bar, a pair of nose-clamping jaws pivotally mounted on said levers, and a pair of single-coil springs each encircling one of the pivots that connects said one of said jaws to the contiguous one of said levers, each of said springs being operatively engaged with the adjacent lever and jaw to hold them yieldingly in their normal position relative to said bridge-bar.

3. An eye-glass mounting comprising a bridge-bar, intermediary levers each provided with abutments, a pair of nose-guards each pivotally secured to one of said intermediary levers adjacent to said abutments and thereby limited in its movements on its pivot, a pair of supporting members each movably secured to said bridge-bar and having one of said intermediary levers pivotally secured thereon, and elastic means to hold said intermediary levers in their normal relation to said supporting members.

4. An eye-glass mounting comprising a bridge-bar having shoulders fixed thereon, a pair of supporting members each having a shoulder fixed thereon and being pivotally secured to said bridge-bar at a point adj acent to one of said shoulders of the bridgebar, a pair of jawmembers each pivotally secured to one of said supporting members and having an arm in contact with the adjacent shoulder of said bridge-bar, and springs each engaged with one of said shoulders of the supporting member and with the adjacent jaw-members and with the pivot of the latter and being cooperative therewith to yieldingly hold the supporting member and jaw-member in their normal position, each said shoulder of the bridge bar being cooperative with the contiguous arm of one of said jaw-members to turn this j aw-member 011 its pivot when the contiguous supporting member is turned on its pivot.

In testimony whereof I have hereunto set m hand.
